Volatile Anesthesia for Carotid Endarterectomy: Friend or Foe for the Brain?

DESPITE SIGNIFICANT IMPROVEMENTS in the management of patients with cardiovascular disease, stroke remains the second leading cause of death worldwide.1 Ischemic strokes account for 87% of all strokes, whereas 10% result from intracerebral hemorrhage, and 3% are subarachnoid hemorrhage strokes.

CONCLUSIONS: The prevalence of stroke in this cohort was 3.1%. Ischemic strokes had a bimodal presentation, occurring either early after SLE diagnosis or after a several-year delay. Half of the hemorrhagic strokes occurred>10 years after the diagnosis of SLE. Clinical outcome was usually good with a relatively low recurrence rate.

Authors: Baranowska B, Kochanowski J Abstract Copeptin, arginine vasopressin (AVP)-associated 39 aminoacid glycopeptide, is a C-terminal part of pro-AVP. AVP acts through V1a, V1b, and V2 receptors. The effect on V1a receptors is connected with arterial vasoconstriction, on V2 with antidiuretic action, and on V1b with the secretion of ACTH, insulin, glucagon. Copeptin is found in the circulation in equimolar amounts with AVP. It is a very stable peptide and easy to estimate. Copeptin is a good diagnostic marker in many disorders in which vasopressinergic dysfunction plays a role in pathogenesis such as a polyu...

AbstractTranslational genomics represents a broad field of study that combines genome and transcriptome-wide studies in humans and model systems to refine our understanding of human biology and ultimately identify new ways to treat and prevent disease. The approaches to translational genomics can be broadly grouped into two methodologies, forward and reverse genomic translation. Traditional (forward) genomic translation begins with model systems and aims at using unbiased genetic associations in these models to derive insight into biological mechanisms that may also be relevant in human disease. Reverse genomic translation...

Time-critical acute ischemic conditions such as ST-elevation myocardial infarction and acute ischemic stroke are staples in Emergency Medicine practice. While timely reperfusion therapy is a priority, the resultant acute ischemia/reperfusion injury contributes to significant mortality and morbidity. Among therapeutics targeting ischemia/reperfusion injury (IRI), remote ischemic conditioning (RIC) has emerged as the most promising. RIC, which consists of repetitive inflation and deflation of a pneumatic cuff on a limb, was first demonstrated to have protective effect on IRI through various neural and humoral mechanisms. It...

ConclusionsThe SPICE multicenter study will investigate 1-year outcomes, ethical issues, as well as care pathways of acute stroke patients requiring invasive ventilation in the ICU. Gathered data will delineate human resources and facilities needs for adequate management. The identification of prognostic factors at the acute phase will help to identify patients who may benefit from prolonged intensive care and rehabilitation.Trial registration: NCT03335995.

This study enrolled 43 patients with VA dissection, and 63 age- and sex-matched healthy subjects were used as the controls. MRA was employed to evaluate the presence of dominant VA and the lateral shift of vertebrobasilar junction in both groups.

The utilization and duration of left ventricular assist device (LVAD) support has increased steadily over the last decade and recent changes in the UNOS heart allocation system, implemented in October 2018, portend a further increase in the duration of mechanical circulatory support for many patients (1). Though four-year survival rates have improved to 60% following LVAD implantation, the leading cause of death in these patients is neurological injury, specifically ischemic and hemorrhagic stroke (spontaneous subarachnoid hemorrhage or intraparenchymal hemorrhage [IPH]) (2).

Conclusion Prophylactic heparin was associated with a nonsignificant increase in any hematoma enlargement and mortality, a nonsignificant reduction in extracranial hemorrhage, and a nonsignificant increase in the incidence of major disability in patients with sICH. It is probably safe to administer heparin to prevent VTE in patients with sICH.

In conclusion, isoflurane protected against BBB disruption caused by carbogen inhalation in mice and rats, but unlike isoflurane-mediated protection against ischemic BBB disruption, the effect could not be explained by anesthesia-induced hypothermia.
